I have a HC-P4241W I purchased 2 1\2 years ago. 6 months ago, I could no longer adjust the green vertical line in the convergence mode. As a result my screen is bowed from top to bottom like ) ( this. I figure its the IC's STK394- 250. Thats not the main problem. Lately I noticed that I am getting yellow streaks starting at the bottom and going up about 6 inches , going across the screen. Not solid all across, just a few streaks. Someone told me to check the collant, the blue is a pale brown color. Any thoughts on how to fix it?
It is a problem with crud built up in my blue lense. I removed the back covered the blue lense, turned on the tv and the haze and streak was gone. I am gonna have to remove the blue crt and take it apart to replace the coolant. I would love to have a manual but I can't find on online. It is a Canadian model I guess, can anyone help me with the removable instrucions? I am an electronics tech but have never touched tvs before. This are my lenses...notice the blue.It is a problem with crud built up in my blue lense. I removed the back covered the blue lense, turned on the tv and the haze and streak was gone.
